2. Change the angle of the Launcher to 60° and shoot the ball again. Call attention to the fact that the ball again
lands on the box (confirming that the ranges are the same).
3. Change the angle to 45° and shoot the ball again to show that the ball now lands further away, missing the
box.
4. Ask the question: What other pairs of angles will have a common range? Will 20° and 70° have the same
range? Will 35° and 55° have the same range?
• This demonstration can be done for any two angles that add up to 90°.
